invention relates to aglazing, structure.

The invention has for an object to provide a novel, r simple and practical glazingstructure adapt fQljhl'lSQMifih the corru ated metal roof- Qing 'orsidill sheets :Of :a building to. provide the building with a window-and-which may beeconomicallymanufactured and erected in the corrugated roof or sides of the building structure or removed therefrom, with minimum effort and at expen e- A further and more specific object of the invention is .tg providea novel glazing unit which may be substituted for one of the corrugated metalvroofing or siding sheets of a building to thereby enablea window to be provided in the building in a simple inexpensive manner and at any desired location in the roofor sides of the building.

A':still further object of the invention is to provide a-noVel 'buildingstruc-ture embodying corrugated roofing or siding sheets togetherwith the novel glazing unit, wherein the latter coop erates with the roofing or siding sheets to form a weather-tight closure for the building.

With these objects in view, and such others as may hereinafter appear, the invention consists in the glazing unit and in the building structure hereinafter described and particularly derugated sheets, the practice has been to overlap the-sides.and ends ofone sheet upon orwunder those of adjacent .sheets,.both with respect to the sidessand endsxthereof. The sheets are -securedto lthebuilding structure, such asto the roof purlings or to thelmembers of the framework. of the walls .of the. building, by clips, and a weather tight structure is provided between adjacent sheetsby riveting together the. overlapped portions of the sheets or by means of: fasteners of various forms. In accordance with the present invention a glazing unit comprising a framework, preferably of metal, having a. glasspane mounted therein, is provided with sheet-likeside members which extend laterally from each side of the frame for a sufficient distance. and which are-curvedor shaped so as to provide at least one corrugation upon each side of the framework, and the end portions of the framework are provided with extension members shaped to correspond to the-corrugations of the next higher and lower corrugated sheets with which the present framework is designed to be used. These extension members are preferably shaped into such corrugated form so as to permit them to overlap upon or to underlie the ends of the next lower fined in the claims at the end of this specification.

In the drawings illustrating the preferred embodiment of the invention, Fig. 1 is a more or less diagrammatic view of a roof or side of a building which is covered with corrugated roofing or siding sheets, such for example as corrugated galvanized steel sheets and illustrating the embodiment in the roof or side of the building of the present glazing unit; Fig. 2 is an enlarged view of the glazing unit shown in Fig. l and portions of the associated adjacent corrugated sheets; and Figs. 3 and 4 are sectional details taken on the lines 33 and 4-4, respectively, of Fig. 1.

Corrugated building sheets have been and are construction of roofs and sides of many buildings and particularly industrial buildings. Such corrugated sheets have beenmade of sheet steel, galvanized steel, aluminum, steel cored protective metal sheets, and also of various cementitious materials, and the corrugations extending lengthwise of the sheets have taken various forms such as rounded corrugations, rectangular corrugations, and V-shaped corrugations. In the ordinary construction of a roof or side of such a building utilizing corcurved or shaped so as to form the and higher sheets respectively. Theends of the corrugated portions of the extension members adjacent the frame are closed and weather-tight.

Referring now to the drawing, it! represents the metal framework of the glazing unit herein shown as comprising a metal member angular in sectional shape andvvithin which a windowpane I2 is operatively supported, being cushioned in any usual or preferred form of resilient waterproof material and being held in place by standard glazing clips M, as shown in Fig. 2. The metal framework may be fabricated in various ways, and preferably is composed of side and end bars 95, IE to which sheet-like side members I 8 and specially shaped end members 20 are welded to form a unitary structure. As herein shown the side members extend upwardly and outwardly for a suflicient distance, and also are equivalent of one corrugation of the corrugated sheets with which the glazing unit is intended to be used in the construction of the roof or side of the building, as will be described. The end members 20 of the metal frame of the glazing unit are provided with upwardly extended portions 22 arranged to terminate in a portion 25 shaped or corrugated to correspond to the corrugations of the next higher and lower corrugated sheets with which the glazing unit is arranged to cooperate. In other words, each end member 20 .of the glazing frame is shaped into corrugated form so that when the glazing unit is substituted for one of the sheets in either the roof or side wall of the building, as shown in Figs. 1 and 4, the upper corrugated portion 24 of the glazing unit is extended under the end of the next higher corrugated sheet 30, while at the lower end. the corrugated end member 20 is arranged to overlap upon the end of the next lower corrugated sheet 32, suitable fastening devices as rivets 34 being provided to connect the sheets 30, 32 with the end portions of the glazing frame and to complete the roofing or siding structure. The

upwardly extended portions 20 of each end mem-'' ber form in efiect closures for the ends of the corrugations of the end members to provide a water and weather-tight structure, and when the unit is embodied in the roof or side of the building, the end portions form an effioient water shed across the unit from the next higher sheet onto the corrugations of the next lower sheet.

As above stated, the present glazing unit enables the erection of corrugated roofing or siding, with windows disposed in any desired loca tion, in an economical, simple and practical manner, and in addition the glazing unit may be substituted for one of, the corrugated sheets of either the roofing or siding of an existing structure when it is desired to provide a window in any particular location in the building.

While the preferredembodiment of the invention has been illustrated and described, the invention may be embodied in other forms within the scope of the following claims.

Having thus described the invention, what is claimed is:

1. A unit for use in building covering structure embodying corrugated building sheets, comprising a recessed open metal frame adapted to have a glass pane mounted therein, said metal frame being provided with side members projecting laterally from opposite sides of the frame and having portions shaped to provide at least a portion of a longitudinal corrugation in each side member, said frame being provided with end members having spaced hollow portions raised above the plane of the frame and having valleys therebetween with the bottoms of the valleys slightly above the outer face of the glass pane when mounted therein, said hollow portions and valleys being shaped to substantially conform to conventional corrugated building sheets and the raised portions having their inner ends closed, whereby when the unit is disposed between corrugated building sheets the valleys between said raised portions form substantial continuations of the valleys of a next higher and lower corrugated building sheet to thereby provide an efficient unobstructed water shed across the unit from the next higher sheet onto the corrugations of the next lower sheet.

2. A unit as defined in claim 1, in which the inner ends of the raised portions are closed by wall portions sloping inwardly and downwardly toward the metal frame.
